Description
Technical field
The present invention relates to medical apparatus technical field, specially a kind of intelligent transfusion drips speed control unit.
Background technique
Venous transfusion is most important a kind of infusion model in the current clinical treatment in China, in practical work, medical care people
Member is usually to be manually adjusted by the pulley on rotation infusion apparatus to drop speed by experience and observation.
Since people's constitution is different, adaptable transfusion speed is also different, when medical staff will be infused according to patient body
After speed regulates, with the variation of medicine bottle inner liquid medicine amount, overpressure of being infused also is changing, this, which will affect, has initially debugged
Transfusion speed makes patient not feel good, therefore we have proposed a kind of intelligent transfusion drop speed control units to solve the problems, such as.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of intelligent transfusions to drip speed control unit, there is control
The effect of pressure.
The present invention adopts the following technical scheme that a kind of intelligent transfusion drips speed control unit for realization technical purpose, including
Damper box plays the role of adjusting pressure, and the viscous of the damper box is glutinous partition, offers at the top of the partition logical
Hole, the through-hole inside are connected with movable block, and viscous stick in the outside of the movable block has limit plate, and the diameter of limit plate is greater than through-hole
Diameter, prevent movable block to be detached from partition, offer connecting hole at the top of the movable block, play down space on connecting partition
Effect.
Viscous stick in the bottom of the movable block has spring, and viscous stick in the bottom of the spring has floating block, the bottom of the damper box
Liquid outlet is offered, gluing is glued in the outside of the liquid outlet four fixed links, and gluing to stick between four fixed links has supporting plate,
It is welded with guide post at the top of the supporting plate, guiding role is played to floating block.
The top and bottom of the damper box viscous stick has perfusion tube, and viscous stick in the outside of the perfusion tube has seal box, institute
It states and is plugged with piston on the right side of seal box.
As optimization, the partition is located at the middle part of damper box, and the limit plate is distributed in the two sides of partition, the connection
The lower opening in hole is located at the side of movable block, and movable block and through-hole are in close contact.
As optimization, the guide post runs through floating block and spring, and the floating block is located at the surface of liquid outlet, floating block it is straight
Diameter is greater than the diameter of liquid outlet, and the junction of the piston and seal box is provided with screw thread.
As optimization, the part that the perfusion tube is located in seal box is provided with air bag, and lower section perfusion tube and damper box connect
The diameter for meeting place is greater than the diameter of liquid outlet, and the diameter of top perfusion tube is greater than the diameter of lower section perfusion tube.
As optimization, the damper box, partition, movable block, spring, floating block and fixed link are all made of nontoxic material
It is made.
The present invention have it is following the utility model has the advantages that
1, the intelligent transfusion drips speed control unit, by the installation and adjustment box on perfusion tube, in use, recipe under partition
Liquid is oozed by liquid outlet, and liquid level slowly declines, and floating block descends through spring and pulls movable block, and the elastic force of spring is not at this time
It is enough movable block pullling out through-hole.
To a certain extent (floating block need to keep certain distance with liquid outlet), floating block passes through spring for liquid level decline below partition
Movable block is pulled, the elastic force of spring is enough to pull movable block into out through-hole at this time, connecting hole lower opening removal through-hole, on partition
Lower perforation, partition top medical fluid are flowed to below partition by connecting hole.
Liquid level slowly rises below partition, and floating block pushes up movable block by spring, when liquid level rising to a certain extent,
The elastic force of spring is greater than the frictional force between movable block and partition, and movable block is headed into through-hole, and partition separates again up and down, this
Sample is separated medicine bottle and human body using partition, prevents infusion overpressure from converting with the transformation of medical fluid in medicine bottle, makes infusion speed
Degree keeps stablizing, and improves the comfort of patient.
2, the intelligent transfusion drips speed control unit, by the fixed connection and sealing box on the outside of the perfusion tube of lower section, needs to add
When fast flow velocity, piston is rotated clockwise, piston is moved right by screw thread, and pressure is lower in seal box, air bag expansion, perfusion tube
Flow velocity accelerate, when needing to slow down flow velocity, rotate counterclockwise piston, in seal box pressure increase, balloon contraction, the stream of perfusion tube
Speed slows down, and in this way by pressure control air bag, prevents perfusion tube by traditional idler wheel compressive strain, influences the normal stream of perfusion tube
Speed.
3, the intelligent transfusion drips speed control unit, by the way that floating block is arranged in the top of liquid outlet, when medical fluid stream in medicine bottle
Complete, when forgetting replacement, because supplementing without medical fluid, the medical fluid in damper box has also slowly flowed, and floating block loss of buoyance falls on out liquid
Above mouthful, liquid outlet is closed, is flowing medical fluid in perfusion tube not, air enters human body after preventing medical fluid stream complete in this way, mentions
The high safety of infusion.
